Plant Profile: Rhododendron cumberlandense

The Cumberland Azalea is native to the Cumberland Plateau, extending from Kentucky down through Tennessee and into the mountainous regions of Georgia, Alabama, and North Carolina. Its blossoms, which can vary in color from yellow-orange to a rich red, typically bloom between June and July. This shrub is known for its ability to hybridize with other azalea species, contributing to its diverse color palette. It typically reaches heights and widths of 3 to 7 feet and can form dense clusters. Propagation is most successful through seeds, as starting from cuttings can be quite challenging.

This azalea thrives in full sunlight in northern regions but prefers partial shade in the southern areas. During dry spells, it requires additional watering. For optimal growth, it should be planted in well-drained, moist, acidic soil rich in humus, and only light pruning is recommended. It is an excellent choice for woodland and native gardens, whether as a standalone specimen or in groups.

While the Cumberland Azalea may be mistaken for the Flame Azalea, it can be distinguished by its smaller flowers and later blooming period.

Habitat: Found in balds and on exposed or moist slopes.
